Unexpected Turbulence for the S-MODE Airborne Instruments

DopplerScatt requires precise knowledge of its position and orientation so that its radar data that it collects can be processed on board and on the ground. These data are what we call navigation data and they come from a Global Positioning System/Inertial Motion Unit (basically a GPS) instrument aboard the DopplerScatt instrument. After the power on, DopplerScatt was unable to process data onboard. Post landing data were transferred to a ground server where they will be evaluated for usability. 

Instruments in the Sea and Sky: NASA’s S-MODE Mission Kicks off 1st Deployment

Using instruments at sea and in the sky, the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) team aims to understand the role these ocean processes play in vertical transport, the movement of heat, nutrients, oxygen, and carbon from the ocean surface to the deeper ocean layers below. In addition, scientists think these small-scale ocean features play an important role in the exchange of heat and gases between air and sea.

NASA aircraft to help study oceans

An aircraft from NASA Armstrong Flight Research Center is taking part in a study of small ocean eddies, swirling areas of water that scientists believe impact how the ocean affects climate change.

The Sub-Mesoscale Ocean Dynamics Experiment, or S-MODE, uses a combination of instruments taking measurements from the air, the ocean surface and underwater to study these spiraling eddies that were first observed from space during the Apollo 7 mission.

NASA launches ocean research mission off San Francisco

The organisation better known for its space programmes seeks to find out in what way oceans are involved in climate change 100 miles off the San Francisco coast. As part of the mission, NASA has one ship, two airplanes, numerous robotic research vehicles and saildrones involved.
